Abstract
The present invention designs a kind of method for realizing that DHCP is adaptive, zero configuration can be reached the standard grade in the network for having Dynamic Host Configuration Protocol server using the equipment of the mechanism, ignores the influence of VLAN.When this equipment is when zero configuration pattern accesses network, dhcp discover probe messages can be actively sent into network, it obtains establishing with dhcp servers using correct port and VLAN after responding and connect, continue the interaction of DHCP protocol until equipment is assigned to IP address, then equipment cures three layer interfaces and its IP and gateway, establishes fixed management passage.
Description
Technical field
The present invention relates to the fields DCN, are related to a kind of technology that DHCP zero configurations are reached the standard grade, and specially a kind of realization DHCP is adaptive
The method answered.
Background technology
DHCP protocol is a kind of means of common LAN distribution IP address, is usually used in DCN（Data
Communication Network, data communication network）Management, but drawback there are one it, cannot in the network there are VLAN
It realizes that zero configuration is reached the standard grade, needs three layer interfaces in client to be configured, IP address can be got from network.This hair
It is bright to be improved for DHCP protocol, the IPRAN equipment of the zero configuration automatic wire charging in the network for having VLAN can be made, and can be solid
Change and configures accessible linking DHCP protocol.The invention is applied to reaching the standard grade for unicom operator IPRAN equipment, can adapt to service automatically
The configuration at end, and need not individually occupy interface.
Invention content
The present invention designs a kind of method for realizing that DHCP is adaptive that provides, and the evolutionary approach based on DHCP protocol completes connection
The DCN management functions of logical operator IPRAN equipment.
The present invention adopts the following technical scheme that, a method of realizing that DHCP is adaptive, including applied to unicom
The IPRAN equipment of operator, configuration include the following steps：
According to networking requirement, server end carries out normal Dynamic Host Configuration Protocol server address and address pool configuration, and server end does not limit to
Device type；
Equipment applied to distal end, which is only dispatched from the factory, to be configured, i.e., the configuration of no any business；
Remote equipment accesses network, passes through the adaptive automatic wire charging to port and VLAN；It is characterized in that the stream of automatic wire charging
Journey is as follows：
Remote equipment accesses in network, and totally 4095 of 0 to 4094 vlan can be sent automatically by all available links
Dhcp discover messages；
When equipment receives the response of a dhcp offer, then the port for receiving message and VLAN are parsed, is created that based on should
The sub-interface of port+VLAN, and continue the content interaction of DHCP protocol（And respond dhcp by the way of socket communications
Requst messages, and continue the not complete agreements of dhcp and continue to interact）, until IP address is allocated successfully；
Then equipment cures the configuration of this sub-interface, and will（What DHCP protocol was got）Gateway is issued to routing table, matches
Set a default route.
The configuration preserved is needed to include：Sub-interface, sub-interface IP address, default route.
Evolutionary approach based on DHCP protocol includes：The IPRAN equipment access DHCP server side of zero configuration has been configured
Network in, totally the 4095 of 0 to 4094 vlan can be sent using general message transmitting party formula automatically by available link
A dhcp discover messages.If equipment has existed configuration, then it is assumed that be that network management path had been got through, no longer undergo this
One process is managed by original configuration.
It is an advantage of the invention that：The present invention is used compared with general DHCP protocol and is more convenient, and can make equipment zero configuration
It reaches the standard grade, adaptively obtains VLAN and port, without manual configuration, reduce artificial consumption.Automatically create three layers of DCN
Mouth can be not take up special communication port on service port；And the bandwidth also very little that the channels DCN occupy, it can ignore not
Meter.
Description of the drawings
Fig. 1 is the flow chart that DCN management is realized in present invention design.
Fig. 2 is the specific implementation networking diagram that the present invention designs.
Specific implementation mode
As shown in Figure 1, a kind of method for realizing that DHCP is adaptive, sets including the IPRAN applied to unicom operator
Standby, configuration includes the following steps：
According to networking requirement, server end carries out normal Dynamic Host Configuration Protocol server address and address pool configuration, and server end does not limit to
Device type；
Equipment applied to distal end, which is only dispatched from the factory, to be configured, i.e., the configuration of no any business；
Remote equipment accesses network, passes through the adaptive automatic wire charging to port and VLAN；It is characterized in that the stream of automatic wire charging
Journey is as follows：
Remote equipment accesses in network, and totally 4095 of 0 to 4094 vlan can be sent automatically by all available links
Dhcp discover messages；
When equipment receives the response of a dhcp offer, then the port for receiving message and VLAN are parsed, is created that based on should
The sub-interface of port+VLAN, and continue the content interaction of DHCP protocol（And respond dhcp by the way of socket communications
Requst messages, and continue the not complete agreements of dhcp and continue to interact）, until IP address is allocated successfully；
Then equipment cures the configuration of this sub-interface, and will（What DHCP protocol was got）Gateway is issued to routing table, matches
Set a default route.
Below in conjunction with Fig. 2, the present invention will be described, and preferred embodiment described below is only used for describing and explaining this
Design, does not limit to the design.
Fig. 2 is the specific implementation networking diagram that the present invention designs.
Webmaster PC, Dynamic Host Configuration Protocol server and remote equipment to be reached the standard grade access common Layer2 switching in same LAN
In machine.
IPRAN local side apparatus uses GE0/1 mouthfuls of webmasters, and it is logical to establish the management with PC by network segment 192.168.0.0/24
Road.Dhcp server functionality is opened on GE0/1.10 simultaneously, distributes the address pool of 10.11.1.0/28.
After far-end IP RAN equipment accesses in network, the configuration file changed is judged whether, if without configuration file,
To all available links using totally 4095 dhcp of the vlan of general message transmitting party formula transmission 0 to 4094
Discover messages have on interchanger configuration vlan 10 to pass through, even if interchanger allows all vlan tag to pass through here,
Server end will not respond to these messages.After message wherein with vlan tag10 is sent to IPRAN local side apparatus, office
End equipment responds DHCP offer messages.Far-end IP RAN equipment judges to receive port and the vlan of message after receiving back message
Tag is created that the sub-interface of ge0/2.10, and socket is then set up with server and is connect and continues interactive DHCP protocol, distribution
A default route is issued further according to the gateway that server is specified to IP address 10.11.1.2, next-hop is directed toward server
ip10.11.1.1.Ge0/2.10 and its IP address and default route are preserved and are configured by end-use device, are thus built automatically
Available network management path is erected.
Network management path between IPRAN local side apparatus and remote equipment, can be on dedicated chain road, can also be with business
Shared link is not take up individual channel.
